Product details
Overview
XC17S100APD8I from AMD (formerly Xilinx) is a serial PROM device designed for configuration of Spartan-3 FPGAs. It provides 1 Mbit (128 K × 8) of non-volatile memory, supports 3.3 V operation, and features a serial peripheral interface (SPI) with clock rates up to 25 MHz. It is used in industrial control systems requiring reliable FPGA bitstream storage.
For engineers reviewing the XC17S100APD8I datasheet, pinout, applications, or equivalent options, key selection criteria include SPI timing compliance, 3.3 V VCC tolerance, PDIP-8 package compatibility, and bitstream integrity under temperature cycling.
Technical Context
This PROM operates exclusively in master SPI mode for FPGA configuration, with no internal oscillator or address decoding logic - all addressing is handled by the host FPGA during power-up initialization. Data readout follows standard SPI phase/polarity (CPOL=0, CPHA=0) timing.
It implements a simple sequential read architecture: once CS# is asserted and a READ instruction (0x03) is clocked in, data streams continuously from address 0x00000 until CS# is deasserted. No write-enable or status register access is supported in normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (128 K × 8), sufficient to store full bitstream for Spartan-3 XC3S1000 and smaller devices |
| Interface | 4-wire SPI (CS#, CLK, DI, DO), no dual/quad mode support |
| VCC Range | 3.0 V to 3.6 V - matches Spartan-3 core I/O voltage, eliminates level-shifting |
| Max Clock Frequency | 25 MHz - enables sub-100 ms FPGA configuration time at typical bitstream sizes |
| Access Time | 60 ns - defines minimum CLK period for reliable data sampling during read |
| Operating Temp | –40 °C to +85 °C - qualified for extended industrial environments |
Pinout & Package
XC17S100APD8I is housed in an 8-pin plastic dual in-line package (PDIP-8) with 0.3 inch body width and 0.1 inch pin pitch. Pin functions are electrically and mechanically defined per Xilinx DS029 v2.5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI transaction; must be held low for entire read cycle |
| 2 (DO) | Data Output | Serial output of configuration data; high-impedance when CS# is high |
| 3 (VCC) | Power Supply | 3.3 V supply input; requires local 0.1 µF decoupling capacitor |
| 4 (GND) | Ground | Reference return path for VCC and I/O signals |
| 5 (DI) | Data Input | Used only for instruction loading (e.g., READ command); tied high or pulled up externally |
| 6 (CLK) | Serial Clock | Input clock driving SPI data transfer; edge-triggered on rising edge |
| 7 (HOLD#) | Pause Control | Active-low; suspends ongoing read without resetting internal address counter |
| 8 (WP#) | Write Protect | Active-low; permanently tied high in configuration-only use to prevent accidental overwrite |
Key Features
| Feature | Design Value |
|---|---|
| Single 3.3 V supply operation | Eliminates need for dual-voltage regulators in Spartan-3 system designs |
| SPI-compatible serial interface | Reduces FPGA pin count usage versus parallel PROM alternatives |
| Hardware write protection (WP#) | Prevents corruption of stored bitstream during power transients or noise events |
| HOLD# suspend function | Enables multi-device sharing of same SPI bus without address arbitration logic |
| PDIP-8 through-hole package | Supports manual prototyping, rework, and legacy PCB assembly processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCF01SVO20C | 20-pin VSOP package; supports JTAG and SPI; 1 Mbit density; 2.5 V/3.3 V dual supply | Requires board redesign for surface-mount layout and different pinout; supports in-system programming | Choose if JTAG reconfiguration capability or space-constrained PCBs are required |
| ATMEL AT17LV010-10PU | PDIP-8 package; 1 Mbit; 3.3 V only; max CLK = 10 MHz; no HOLD# or WP# pins | Lacks suspend and hardware write protection; slower configuration speed limits FPGA startup time | Choose only for cost-sensitive, non-critical applications where feature reduction is acceptable |
Compared with XCF01SVO20C and ATMEL AT17LV010-10PU, XC17S100APD8I offers optimal balance of through-hole compatibility, SPI performance, and hardware-level configuration security for legacy Spartan-3 deployments.

FAQ
Is XC17S100APD8I compatible with Spartan-3E FPGAs?
Yes, XC17S100APD8I is fully compatible with Spartan-3E devices such as XC3S100E and XC3S500E. Its 1 Mbit capacity and 3.3 V SPI interface meet the configuration requirements specified in Xilinx UG071 v2.5. The XC17S100APD8I uses identical timing and command set as required for Spartan-3E master-mode startup.
Does XC17S100APD8I support in-system programming (ISP)?
No, XC17S100APD8I does not support in-system programming. It is a one-time programmable (OTP) PROM with factory-programmed content. Programming requires a dedicated PROM programmer prior to soldering. The XC17S100APD8I lacks internal erase/write circuitry and has no JTAG or ISP interface capability.
What is the maximum allowable CLK frequency for reliable operation of XC17S100APD8I?
The maximum guaranteed CLK frequency for XC17S100APD8I is 25 MHz at VCC = 3.3 V and TA = 25 °C, per Xilinx DS029 v2.5. Operation above this frequency may result in setup/hold violations. The XC17S100APD8I datasheet specifies 60 ns access time, which corresponds to a 16.7 MHz practical limit under worst-case voltage and temperature conditions.
Can XC17S100APD8I be used with Spartan-6 FPGAs?
No, XC17S100APD8I is not compatible with Spartan-6 FPGAs. Spartan-6 requires configuration via the newer XCFxx or Platform Flash families supporting faster SPI modes and different command sets. The XC17S100APD8I lacks the necessary instruction set and timing parameters defined in UG380 for Spartan-6 configuration.
What is the purpose of the HOLD# pin on XC17S100APD8I?
The HOLD# pin on XC17S100APD8I allows pausing an active SPI read operation without resetting the internal address counter. When asserted low, data output halts and the next CLK edge resumes from the same address. This enables multi-device SPI bus sharing. The XC17S100APD8I HOLD# function is defined in DS029 section 4.3 and requires no external pull-up.
